The basis for #SwearEngine is that malware developers are developers too. The catharses in their malware code manifest in a multitude of coarse expressions. Thus we can use the presence of swear words as a "weak signal" to surface interesting files. #threathunting

You may balk at #SwearEngine for being #basic but consider that this rule, looking for PEs with one single "fuck", detects malware samples used by APT5, APT10, APT18, APT22, APT26, Turla, FIN groups, dozens of UNC espionage clusters. Too many to list.

At least one single "fuck" is present in some samples of the following malware families: AGENTBTZ, ASCENTOR, ZXSHELL, SOGU, TRICKBOT, GHOST, VIPER, WANNACRY, WARP, NETWIRE, COREBOT, REMCOS, VIPER, ORCUSRAT, PONY, etc. I can't even name the coolest ones. There are hundreds.
